SHIELD FOR SPRINKLER-HEADS.

Specification of Letters Patent.

Patented July 12, 1910.

To all whom it may concern:

Be it known that we, FRANK E. Orrrz and BENJAMIN F. CALDWELL, citizensof the United States, residing at Pomona, in the county of Los Angelesand State of Cali-- fornia, have invented certain new and usefulImprovements in Shields for Sprinkler- Heads; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in attachments tosprinkler heads for directing the water away from a person desiring toapproach the sprinkler head and forming a shield whereby the water, asit is sprayed from the perforations, may be directed in any desireddirection.

Our invention comprises various details of construction, combinationsand arrangements of parts which will be hereinafter fully described andthen specifically defined in the appended claims.

We illustrate our invention in the accompanying drawings, in whichFigure 1 is a perspective View of our improved shield for attachment tosprinkler heads, and Fig. 2 is a sectional View longitudinally throughthe device showing the adjustment of the cylinder in dotted lines. Fig.3 is a slight modification of the shape of the sprinkler head.

Reference now being had to the details of the drawings by letter, Adesignates a sprinkler head which is made in the form of an elongatedloop having a late-rally eX- tending bulged portion B with series ofperforations D formed therein through which water is adapted to besprayed. Communicating with said loop is a branching pipe E havinginterior threads and adapted to be fastened to the coupling of a hosepipe. Said loop is provided with annular flanges H, and K designates acylindrical shield, the ends of which are provided with apertures N forthe reception of the cylindrical piping of which the loop is made, saidpipe forming a journal bearing about which the cylinder is adapted torotate. It will be noted that said cylinder has substantially half ofits circumference cut away to allow the water to freely spray where theclosed part of the cylinder does not come immediately in front of theperforations in the sprinkler head.

In operation, the cylindrical portion of the device is adapted to restupon the ground and, in the event of it being desired for a person toapproach the spray head for any purpose, such as to take hold of thesprinkler head, by rotating the cylinder so that the closed part of thecylinder will come adjacent to the perforations, the cylinder will actas a shield and prevent the spray from coming in contact with the personhandling the sprinkler head. By the provision of the device, it will benoted that means is afforded whereby the direction of the spray may beregulated, that is to say, if a person desires to sprinkle over acertain surface, it may be done by the regulation of the shield relativeto the perforations.

WVhat We claim to be new is 1. In combination with a hollow loop shapedsprinkler head, a cylindrical shield journaled thereon adapted to swingabout the perforated portion of the sprinkler head.

2. In combination with a hollow loop shaped sprinkler head, acylindrical shield journaled thereon adapted to swing about theperforated portion of the sprinkler head, a portion of the circumferenceof said cylinder being cut away.

8. In combination with a hollow loop shaped sprinkler head, acylindrical shield journaled thereon adapted to swing about theperforated portion of the sprinkler head, flanges upon the sprinklerhead adapted to bear against the outer faces of the ends of saidcylinder.

4. In combination with a sprinkler head formed in the shape of anelongated hollow tubular loop, a portion of which has a lat- Intest1mony whereof We, hereunto afiixed our signatures in the presence oftwo Wit- HGSSBS.
